Title: Visual display providing three=dimensional effect without requiring spectacles - directs images from two cameras using electron guns, through slotted mask and onto screen with lens in front having strip prism form
Inventor: HENTSCHKE SIEGBERT PROF DR ING
IPC: H04N13/00
Filed: 1991-04-29
Abstract: The visual display provides a stereoscopic viewing effect without the user having to wear special spectacles. The screen image is produced by three colour electron guns directing output through a slotted mask and onto photosensitive screen (5). The images projected are based upon that obtained with two cameras. The stereoscopic effect is produced by a lens (8) located in front of the screen that has a surface with parallel prism shaped strips (8a). The eyes of the observer (6, 7) focus on the points (9, 10) that depend upon the refraction caused by the lens. An alternative lens profile may be used or can be replaced by a masking bar pattern. A sensor may be provided for detecting the position of the observer so that a real-time video computer can generate corresp. right and left image perspectives having unnoticable delay. USE - For medical scanning e.g. of tumorous tissue.

Title: Central locking arrangement for vehicle - has sensor to detect occupants andinhibit locking unless vehicle is empty
Inventor: KUHN STEFAN
IPC: E05B65/36
Filed: 1991-08-28
Abstract: The central locking system is operated when the ignition key is removed and one door is locked.  To prevent locking anyone inside the vehicle a sensor (15) monitors if any seat is occupied and then blocks the locking action, unless the vehicle is empty.  The sensor can be a simple pressure switch under each seat, requiring a set pressure to operate. A centrally mounted IR sensor can scan all the seats from a simple roof mounting.  The sensor angle is set to exclude any thermal sources, e.g. on the dashboard.  The safety system can be included in conventional central locking systems. ADVANTAGE - Improved safety; no risk of locking persons in vehicle.

Title: Electronic energy door surveillance for intruder alarm system - uses latch plate and contacts to provide alarm signal in response to abnormal contact operating sequence
Inventor: ARNDT KURT DIPL ING
IPC: G08B13/06

Title: Abutment for swivel bearing of strip-like tension bar - has opening with elastically non-deformable edge area where tension bar is supported in stressed state.
Inventor: PSCHEIDT BERTHOLD
IPC: F16B2/24
Filed: 1992-03-24
Abstract: The opening through which the first barb (10) of the tension bar is inserted is aligned at right angles to the tension direction (S) of the bar (5).

The edge area or flap (7) of the opening (8) opposite the support edge in the tension direction can be elastically deformable in order to create the snap closing action. The opening (8) is pref. a gap with two opposite edges of which one forms the supporting edge. USE/ADVANTAGE - Where space restricts, tension bar can now be snapped into abutment through snap force applied perpendicular to tension direction of bar.
Patent DE-4212406-A1 (DE)
Inventor: BAUMGARTNER HANS
IPC: F16D65/56
Filed: 1992-04-13
Abstract: The invention relates to a pneumatically operated disc brake having a brake caliper surrounding a brake disc on one side of which is arranged a brake application device which, via at least one adjusting spindle and a pressure member fitted on its end nearest the brake disc, acts on a brake pad fitted in the pressure side of the brake caliper so as to move in relation to the brake disc. An adjuster coupled integrally in rotation with the adjusting spindle (73) keeps the clearance which changes as the brake pad wears substantially constant and is connected to an externally operable rotary drive device by means of which the adjusting spindle (73) may be returned to its initial position. In order to prevent the incorrect changing of brake pads from adversely affecting the operation of the brake, there is a stop (730) which essentially acts circumferentially on the adjusting spindle (73) when the latter is in its initial position.

Patent DE-4225397-A1 (DE)
Inventor: HOFMANN WILFRIED DR ING
IPC: H02P21/00
Filed: 1992-07-29
Abstract: The invention is based on a method for automatic regulation of a converter-supplied three-phase machine, in the case of which method the actual values of the stator flux components and of the torque are formed from the stator current and stator voltage components, and the stator voltage vector which is to be connected via the invertor is preselected from the position of the stator flux vector. The object is to develop such a method in such a manner that the entire rotation speed adjustment range can be controlled with very good dynamic and steady-state characteristics. This is achieved in that the regulation differences of the stator flux magnitude ( DELTA  psi ) and of the torque ( DELTA m) are supplied to a fuzzy-logic regulator which determines the voltage vector (V nu ) to be connected, with the associated pulse times (T nu ) over a fixed pulse period (t), and produces the actuating signals (sa, sb, sc) via pulse-width modulation (7). <IMAGE>

Title: Increasing working life of electrolytic bath contg. heavy metals - by removing harmful organic material with adsorption polymer which is then itself regenerated with acid or alkali
Inventor: LIEBER HANS-WILHELM PROF DR
IPC: C25D21/18
Filed: 1992-12-11
Abstract: The working life of a heavy metal electrolytic bath is prolonged by removing harmful organic material using an adsorption polymer which itself is regenerated by treating with inorganic acid or alkali. In special cases where the polymer is not easily regenerated, the latter is oxidatively pretreated with H2O2 solution followed by treating with NaOH solution. The organic material removed during regeneration of the polymer can be reconstituted and reused by subjecting it to a redox process, esp. UV oxidation treatment in which a mineralisation of the material takes place. The acid used to regenerate is HCl, H2SO4 or HNO3 and the alkali is NaOH or KOH in conc. of 2-10%. ADVANTAGE - The adsorption polymer is regenerated without using an organic solvent.
